| Glossary Term | Definition |
| RADIO FREQUENCY | Non-optical automatic identification devices that use radio waves to transmit data. |
| RADIO FREQUENCY DATA COMMUNICATION (RFDC) | Handheld or vehicle mounted units that send and receive messages by radio frequency. Information from the units is displayed on a screen for workers and allows real-time, two-way exchange of data between terminals when one terminal is mobile and the other is a host computer at a remote location. |
| RADIO FREQUENCY IDENTIFICATION (RFID) | The use of small radio transponders that are activated by a reading transmitter. The transponder carries a unique ID code or other information in its memory and can be read at a distance without line of sight. |
| RADIO FREQUENCY TAG | An electronic tag capable of receiving, storing and/or transmitting digital information. |
| RADIO FREQUENCY TERMINALS |
A wireless portable device used to interact with a remote host computer. |
| RANGE | The distance at which a tag can be successfully read or written to by the reader. |
| READ | The process of retrieving the information stored on an RFID tag. |
| READ RANGE | The distance from which a reader can communicate with a tag. |
| READ RATE | The maximum rate at which data can be read from a tag, generally expressed in bits per second (bps). |
| READ/WRITE | Refers to tags that can receive new data while they are attached to product, such as tags that store a record of shipment information. |
| READABILITY | Refers to the ability of a reader to obtain data from a tag, generally under difficult conditions. |
| READER | The device that retrieves information from tags using radio waves. Readers generally receive data from tags and transmit data to host computers or peripheral devices, such as a printer. |
| READER/WRITER | A device that can both retrieve information from a tag and write information to a tag. |
| REFLECTANCE | The ratio of the amount of light of a specified wavelength or series of wavelengths reflected from a test surface to the amount of light reflected from a barium oxide or magnesium oxide standard. |
| RELEASE LINER (BACKING) | The portion of the pressure sensitive label which supports and holds the facestock and adhesive until application to the intended surface is needed. |
| REMOVABLE ADHESIVE | An adhesive characterized by relatively high cohesion strength and low ultimate adhesion. It can be removed easily from most substrate surfaces. Some adhesive transfer could take place, depending on the affinity of the adhesive to the surface. |
| REPEATER | A device used to extend cabling distances by regenerating signals. |
| RESIDUE | Adhesive left on a substrate when a decal is removed. |
| RESOLUTION | The narrowest element dimension distinguished by a particular reading device or printed with a particular device or method. |
| RESIN RIBBON | Scratch and chemical resistant. Suitable for coated synthetic labels. |
| RIBBON | A cloth or plastic tape coated with several layers of material, one of which is ink-like, that produces the visible marks on a substrate. Used on formed font impact, dot matrix, thermal transfer and hot stamp printers. Also called foil. |
| ROUTER | The main device in any modern network that routes data blocks from source to destination using routing tables and determining the best path dynamically. It functions as an addressable entity on the LAN and is the basic building block of the Internet. |
| RSS SYMBOLOGIES | Reduced Space Symbology; a family of linear symbologies that are restricted and subject to compliance with the EAN International (EAN) and Uniform Code Council, Inc. (UCC) rules. Any member of the RSS family can be printed as a stand-alone linear symbol or as a Composite symbol with an accompanying 2D Composite Component printed directly above the RSS linear component. |
